When solving an equation with two variables, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
Solve -b - 4b = 8b - 5y - 9 for b in terms of y.
| -\(\frac{2}{3}\)y - \(\frac{5}{12}\) | |
| -1\(\frac{1}{2}\)y + 1 | |
| -1\(\frac{5}{11}\)y - \(\frac{9}{11}\) | |
| \(\frac{1}{9}\)y + 1 |
